While privacy laws around such thinks as spam email have evolved alongside the technological advancements, the same cannot be said about real world privacy.
Current laws were drafted when hand-held video cameras had poor resolution, before surveillance cameras were everywhere, and of course before smart phones.
It used to be that your public movements and actions were never recorded. Now it is almost the opposite – before long they will always be recorded.
New laws are required to stop the misuse of such recordings.
If you, specifically, are being recorded, your permission is required. Exceptions would be law enforcement, licensed security firms, and licensed news reporters. Specifically, means the purpose of the filming, as opposed to you incidentally being filmed.
You own the rights of your public activities for commercial purposes. If you are filmed doing something, say falling down escalators, others cannot sell that footage without your approval. Again, licensed reporters are exempt.
Facial recognition is illegal for commercial purposes, without your prior, specific approval. It can’t be buried away in terms and conditions.
There’d probably also need to be restrictions against some non-commercial use, like Neighbourhood Watch.
Microsoft today predicted such laws, by asking for them:
